Motor Control Module (MCM)

The MCM calculates the battery module SOC and controls the IPU module fan. The SOC is calculated using voltage, temperature, input current, and output current readings from the battery module.

The MCM controls the DC/AC conversion between the battery module 100 V to the 3-phase AC IMA motor.

The MCM also controls the IMA motor assist and regeneration.
